Module name module description
Introduction teaching is divided into two parts: theoretical knowledge teaching and multimedia teaching.
Scene practice
(including voice animation reminding, guiding operation and helping to correct deviation) A. Working face training operation control (including "finger dictation" in 3D)
B, error correction, etc.
C, the actual evaluation and analysis
Common fault handling
Daily maintenance adopts the introduction mode of 3D, voice, text and video.
Mechanical structure
(including auxiliary voice explanation) animation shows the composition and working principle of main components, and 3D panoramic parts are disassembled.
The theoretical examination system automatically draws questions to generate test papers, and the knowledge of fully mechanized mining is assessed and scored.
I. Application prospect
Virtual training mode is a higher-level application of virtual simulation technology (3D technology) and a brand-new interpretation of the application of multimedia technology. Therefore, we have reason to believe that this advanced, safe, economical, low-carbon and energy-saving training mode will become the mainstream mode of coal mine skills training in the future.
"Virtual Training Operating System of Shearer" adopts the internationally advanced graphic function library, which supports the bottom drawing and modeling capabilities. She has conducted extensive research and development on hardware-supported OPENGL technology. The biggest feature is that the system development is not limited by any external environment, and it can realize all kinds of imaginable interactive functions, so that the system has the greatest expansibility and personalized product development.
Second, the content composition
"Teaching instrument for virtual training operation of shearer" consists of two parts: software system and hardware system.
& ltI >, software part
The system includes basic knowledge teaching, finger oral safety confirmation teaching, interactive teaching of scene practice, mechanical structure disassembly, practical examination, intelligent error correction, guiding teaching and other functional modules. The functions of each module are as follows:
1, introductory teaching
(1) Basic knowledge
This paper briefly introduces the relevant knowledge and matters needing attention in the operation of roadheader.
(2) Multimedia video teaching
This paper introduces the relevant knowledge and matters needing attention of roadheader operation through video recording.
2. Situational teaching
Scene teaching includes idling action, preparation before excavation, working state and common fault handling.
(1) null operation
Using the remote controller and lever to control the fully mechanized mining machine in the working face for empty car operation practice, students can intuitively learn and understand the basic operation method, component composition, working principle and workflow connection of shearer, and have a comprehensive understanding of the functions of operating handles and buttons of each part.
(2) Preparation before fully mechanized mining
Before fully mechanized mining, oral finger safety confirmation teaching is carried out in the working face according to the operation rules, and students can gradually carry out the most standardized operation exercises according to the safety operation guidance of 3D animation. When the operation is wrong or irregular, the system will automatically give a warning and guide the correct operation method. Within the specified time, if the preparatory work is not completed or there are illegal operations in the preparation process, it is not allowed to enter the coal mining work state.
(3) Coal mining practice
After the safety preparation before fully mechanized mining is completed, you can enter the coal mining practice. Using the remote control of shearer, scraper conveyor controller, hydraulic support joystick and other operating devices, the mechanical equipment in the working face is controlled on the spot. In case of illegal operation during operation, the system will automatically give a "red warning" and deduct points. The system will calculate the assessment results and give voice comments according to the coal output within the specified time and the number of violations during the completion of the operation.
3, common fault handling and daily maintenance
Using 3D, voice, text, video and other explanations, the causes of common faults of shearer are analyzed, and the corresponding solutions are given in combination with the problems.
4. Mechanical structure
This paper introduces the main parts of shearer in the form of animation.
5. Theoretical examination
Theoretical examination module is a knowledge examination function independent of analog control training in the system. It examines students' mastery of shearer operation knowledge in the form of test questions.
< second >, hardware system:
The hardware system consists of the main console of the shearer, the console of the hydraulic support, two wireless remote controllers of the left and right cutting parts of the shearer, a 28-inch display screen, a high-equipped main PC, an external large-screen display system and an external audio combination.
Third, product advantages:
1. scientific
Traditional practical training, through the mentoring of old workers, is easy to pass on some bad habits or irregular operations, causing hidden dangers of accidents. The virtual training operating system of shearer integrates the safety confirmation method of "finger dictation" according to the requirements of the three major regulations of coal mine. This form of simulated training will strictly regulate the skill operation of workers and make it more scientific and reasonable. Moreover, the interactive control of hardware equipment and software solves the single problem of abstract operation of pure software and pure hardware equipment.
2. Security
Students can realize the seamless link between study and training (work), which obviously shortens the training cycle, and students can quickly adapt to the working environment and put into production as soon as possible, thus avoiding the security risks brought by underground real machine training. The system also gives an alarm prompt and intelligent rectification for illegal operations: it gives an alarm for the operators' irregular operations, and gives a correct operation method guidance prompt, so that safety becomes a habit.
technicalization
Practical assessment, achievement summary and technical grade evaluation: the standard for practical skills assessment to be realized. It can also be used as an objective, just and fair basis for technical competition.
4. Flexibility
Training can be carried out in daytime, rainy, cold and summer, and the training time can be flexibly adjusted according to the situation, thus completely solving the teaching inconvenience caused by weather problems. Moreover, the development of the project can be customized according to the requirements of coal mines.
5. Save training expenses, improve the utilization rate of production equipment and increase production efficiency.
The capital investment for establishing the virtual practice system is one-off, which can be used continuously in the long-term training work after the platform is established, and can also be combined with the existing multimedia teaching equipment for training. Compared with the investment of millions of "training base" project and its actual effect, virtual training operation can greatly save huge capital investment and achieve very significant training effect.
When students learn to operate downhole equipment, it will affect production. Using operators to teach does not need to occupy the production and use of equipment, and also solves the high machine loss and maintenance cost of real machine training.
6, energy saving, low carbon, environmental protection
The electric energy consumed by a set of fully mechanized mining equipment per hour can meet the normal teaching of more than 600 hours of teaching instruments for virtual training operation of shearer.
7. Rich in information
Through computer operation, students not only have "finger dictation" content and practical training, but also have theoretical knowledge learning and assessment, so that learning is both deep and broad. Underground work, especially needs compound talents.
